INVENTOR ATTOR N EY imatented Mar. 14, 1933 HENRY M. KEITH, FHARRISBURG, ILLINOIS OIL AND LIQUID DISPENSING DEVICE Application filedFebruary 23, 1932. Serial No. 594,59?.

This invention relates to liquid dispensing devices and has for theprimary object, the provision of a. device of the above stated characterfor easily and quickly dispensing liquids of any desired characterwithout waste and in predetermined amounts and which is so constructedas to eiciently display the liquid to the purchaser prior to beingdispensed.

l@ lAnother object of this invention is the provision of a dispensingdevice operated by air pressure, whereby liquid may be forced from asupply to a visible measuring receptacle and dispensed therefrom underpressure in desired amounts.

A further object of this invention is the provision of means whereby thedispensing medium may be employed for actuating a control means foreither placing the liquid in o the supply under air pressure or theliquid in the liquid measuring receptacle under pressure and toautomatically vent the receptacle when filling the latter from the suplp N ith these and other objects in view, this invention consists incertain novel features of construction, combination and arrangement ofparts to. be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothefollowing description and accompanying drawings, in which Figure 1 isa side elevation illustrating a liquid dispensing device constructed inaccordance with my invention.

Figure 2 is a fragmentary vertical sectional view illustrating the sameand taken on the line 2 2 of Figure l.

Figure 3 is a detail sectional view taken on the line 3 3 of Figure 2.

Figure 4l is a transverse sectional view taken on the line 4 4 of Figure1.

nig ire 5 is a detail sectional view taken on the line 5--5 of Figure 2.

Tiiigure is a fragmentary sectional view illustrating a check valve forthe liquid intake pipe from the supply to the measuring receptacle.

Referring in detail to the drawings, the numeral 1 indicates tank ordrum for containing lubricatin oils or any other liquid offered for saleand has associated therewith a dispensing device 2 which includes a base55 3 supporting a transparent bowl or cylinder 4, the upper end of whichis closed by a head 5 provided with a clean-out port 6 normally closedby a removable cap Suitable leakproof connections are provided betweenthe ends of the cylinder and the head 5 and base. The base is providedwith a centrally located passage 8 therethrough and in which is formed avalve seat 9 normally closed by a self-seating valve 10. The passage 8is con- 65 nected to a supply pipe ll extending through a suitablestuiiing gland 12 of a supply tank or the supply drum 1. The passage 8is intercepted by a horizontally disposed chainber 13 in which a tube1li is journalled and one end of said tube entends enteriorly of thebase by Way of a stung bon or gland 15 and has secured thereto a hollowarm 16 and the latter being in communication with the tube 14E by ports17. A hollow angularly disposed journal 18 is formed on the arm 16 andhas journalled thereon a coupling 19, the latter being in communicationwith the extension 18 by the ports 20 and is connected to a hose orsimilar element 21. Ahe free B0 end of the hose 2l carries a dispensingnozzle 20 provided with a manually controlled valve 23 whereby theliquid of the cylinder l may be dispensed in desired amounts.

The hollow arm 16 is normally maintained 85 in a vertical position asshown in Figure 1 by a coiled spring 9.4 attached to a bracket 25 on thebase and when in this position7 the tube 14- is so arranged that aprojection 26 is disengaged from the valve 10 allowing the latter toremain in a seated position interrupting the passage between the drum 1and the cylinder 4l.

The base 3 Vhas formed therein an air chamber 27 suitably connected toan air pressure source and has located therein a control valve 28 of therotary type and is actuated by the rotation of the tube 111 by havingthe movable element 29 thereof connected to the tube by a stem 80. Thevalve 28 is provided with outlet ports 31 and 32, the latter named portconnected to a. pipe 33 which is in turn connected to the drum. The port31 is connected to a pipe 34 that is in communication with the cylinder4 by way of a port or passage 35 in the head 5. The head 5 is alsoprovided with a vent opening 36 having a. valve seat 37 and the latterhas associated therewith a self-opening valve 38 normally held in aseated position by a rocker arm 38 pivoted to ay bracket 39 carried bythe head. The rocker arm 38 is pivoted to a push rod 40 slidably mountedin a guide 41 with its lower end in engagement with the arm 16 so thatwhen said arm 16 is disposed vertically, the rocker arm 38 will seat thevalve 38 and close the cylinder 4 to the atmosphere.

A float 42 is slidably mounted in the cylinder 4 and is provided withwashers 43 having frictional contact with the walls of the cylinder. Thefloat is adapted to ride upon the liquid within the cylinder, it beingunderstood that the cylinder 4 in conjunction with the base and head 5forms a visible measuring receptacle, the cylinder 4 being providedWit-h suitable graduations to indicate the amounts of liquid containedwithin the measuring receptacle.

The lower end of the supply pipe 1l is provided with a suitable checkvalve 44 which Will permit liquid to pass from the drum to the measuringreceptacle but which will prevent the liquid from returning to the drum.

In operation when desiring to force the liquid from the drum to themeasuring receptacle, the hollow arm is swung in the arc of a circleagainst the action of the spring 24 by exerting a pull on the hose. Thismovement of the arm imparts a movement to the tube 14 unseating thevalve 10 and at the same time connecting the air pressure from thechamber Z7 to the drum and the air pressure displaces the liquid tromthe drum into the measuring receptacle. As soon as the hose is manuallyreleased, the spring returns the arm 16 to a vertical position cuttingoil" the supply of air pressure to the drum and allowing the valve 10 toseat. The valve 31 then assumes a position to establish communicationbetween the air pressure means and the upper end of the cylinder 4 byway of the pipe 34 placing the liquid in the cylin- 3 der under pressureby the air pressure acting against the float 43, so that. when the valve..53 is manually opened liquid will be rapidly forced from the cylinder.The float moving downwardly in the cylinder wipes the liquid K from thewalls of the cylinder. lVlien the arm 16 is positioned to admit liquidto the cylinder 4 from the dr'um 1, the valve 38 is unseatcd allowingthe cylinder 4 to be vented.

lvhile I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:

1. A liquid dispensing device comprising a visible measuring receptacle,means connecting said receptacle to a liquid supply, means for admittingair pressure to either the liquid supply or the receptacle, and adispensing means Jfor said receptacle and capable oi' actuating themeans for admitting air pressure to the liquid supply or the receptacle.

2. A liquid dispensing device comprising a visible measuring receptacle,a supply pipe in communication with the receptacle and a liquid supply,a self-closing vent valve for the receptacle, an air pressure meansconnected to the receptacle and the liquid supply, a control valve forthe air pressure means, and a dispensing means for said receptaclecapable of unseating the self-closing vent valve and for actuating theair pressure control valve to admit air pressure either to the liquidsupply or to the receptacle.

3. A liquid dispensing device comprising a visible measuring receptacle,av pipe connected to the receptacle and to a liquid supply, aself-closing valve for the pipe, a rotatable t'ube in communication withthe receptacle, a hollow arm carried by and in communication with thetube, a dispensing means connected to said arm, an air pressure meansconnected to the receptacle and to the liquid supply, a control valvefor said air pressure means actuated by the rotation ot' the tube, meanscarried by the tube for unseating the self-closing valve on movement ofthe tube in one direction, a self-opening vent valve for the receptacle,means associated with the selfopening valve for seating the latter bythe arm when in a given position, tension means for normally maintainingsaid arm in the last named position, said air control valve normallyestablishing communication between the receptacle and the air pressuremeans, said tube adapted to be moved in one direction for unseating theself-closing valve and actuating the air control valve to admit airpressure to the liquid supply when the arm is moved by a pull on theliquid dispensing means.
